Dovesti - Rotational Movement

Think a little while about the imagery: the way you would make a top spin. Or, if you were to turn a wheel, the way you could reach out with your arms and turn the wheel surrounding you. The dynamics are extremely different and extremely clear. We might even suggest that you try this in real life, assuming you can find a wheel sufficiently big inside which you can stand.

Now think about it a little bit more. We realize that most people will just say "yup. I got it." immediately. But, even though you understand the idea, we want you to think about it some more, until it's ironed into your brain. Only then, will it help your lead.
